I'm trying to fix the post count bug, so I uninstalled a lot of the add-ons, such as mentions (which was actually disabling the color change thing and various other things). We need to figure out how to bring mentions back without wrecking the side bar and resolve the elusive post count as well.
I went along with something along those lines. But hey, if you want that I suggest you create that thread since this just passed 600 pages, it's time for a new one before this starts weighing down heavy on the database.
